Abstract
A magnet-mounting member for holding permanent magnets against side faces of each claw-shaped magnetic pole has pairs of extreme-end and basal-end hooking tabs for preventing displacement of the permanent magnets in either a basal-end or extreme-end direction. The magnet-mounting member is configured such that a function of the basal-end hooking tabs to prevent displacement of the permanent magnets can be disabled by deforming the basal-end hooking tabs. When the magnet-mounting member is forced onto the claw-shaped magnetic pole, the basal-end hooking tabs go into contact with the permanent magnets and deform outward, whereby the magnet-retaining function of the basal-end hooking tabs is disabled. When the magnet-mounting member has been fully pushed onto the claw-shaped magnetic pole, the basal-end hooking tabs resume an original shape to prevent the permanent magnets from being displaced in either direction.
